Non-broadcast will not work with point-to-multipoint of course unless
you're referring to using "point-to-multipoint non-broadcast" and not
just plain non-broadcast ;-)
With three routers in a hub and spoke design with no point-to-point
subinterfaces, non-broadcast needs four commands relating to OSPF and
two additional frame-relay mappings while point-to-multipoint needs only
three OSPF commands and no additional frame-relay mappings. So which is
easier?

I seem to recall, that did not work on the Frame Relay network without
the
"non-broadcast". I could be wrong. What is the default?
